Authorities went door-to-door overnight ordering thousands more people to seek higher ground as creeks and reservoirs overtopped their banks and sent chest-deep water into neighborhoods.

At least 225 residents were taken Tuesday to dry land and rinsed with soap and water to prevent them from being sickened by floodwaters that had traveled through engine fuel and garbage. No major injuries are reported.

The region is drying out after heavy rains, but flood warnings continue through Saturday morning.
